<h3>The worth after 4 years is $ 680.24</h3>
<em><u>Solution:</u></em>
<em><u>The formula for compound interest, including principal sum, is:</u></em>

Where,
A = the future value of the investment
P = the principal investment amount
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = the time the money is invested
From given,
n = 1 ( since interest is compounded annually)
p = 500
t = 4

<em><u>Substituting the values we get,</u></em>

Thus the worth after 4 years is $ 680.24
Answer:
A is the only solution.
Step-by-step explanation:
A simple way to solve it is to plug in the x and y values
For A, we plug in 2 for x and 3 for y
3-3=5(2-2)
0=5(0)
0=0
Ordered pair A is a solution
For B, plug in 3 for x and 2 for y
2-3=5(3-2)
-1=5(1)
-1 does not equal 5
Therefore only A is a solution
<u>Answer
</u>
Option A) 17cm
<u>Explanation
</u>
Polygon R and polygon S are similar. This means the polygon R and S have equal number of sides.
Step 1 : Find the number of sides of polygon S
The perimeter of polygon S is 64 cm. If one side of polygon S is 8 cm
Therefore, Number of sides of polygon S = 64/8 = 8 sides
and number of sides of polygon R = 8 side
Step 2 : Find the number of sides of polygon R
The perimeter of polygon R is 136 cm,
Number of sides of polygon R = 136/8 = 17 cm
Therefore side length of polygon R = 17 cm
